+Creates a promise that resolves after a given amount of time to the provided value.
+
+- Use the `Promise` constructor to create a new promise.
+- Use `setTimeout()` to call the promise's `resolve` function with the passed `value` after the specified `delay`.
+
+```js
+const resolveAfter = (value, delay) =>
+  new Promise(resolve => {
+    setTimeout(() => resolve(value, delay));
+  });
+```
+
+```js
+resolveAfter('Hello', 1000);
+// Returns a promise that resolves to 'Hello' after 1s
+```
